Setting up your own RuneLite plugin hub
So while I've documented it, I can't take credit for figuring it out as well as any relevant code. That was provided by @Spooky, so thanks a lot to him for providing that!
However, I've made the document to get it done, and referred to the code if you just want the code.
You can read how to do it here: https://github.com/Nozemi/rsmod/blob...-hub/README.md
This allows you to host your own plugin hub, to get plugins like 117HD. Which is plug & play for OpenOSRS Runelite & Official RuneLite.
